To all whom. it may concern.

Be it known that I, AUGUST HORMEL, a citizen of the United States, residing at New York city, county and State of New York, have invented a new and Improved Antiskidding Device for Automobiles and Similar Vehicles, of which the following is a specification Thls invention relates to a novel device for preventing the skiddingof automobiles roadbed is correspondingly increased, and:

said movement is thus effectively checked. The trailer is further provided with readily operable braking means to prevent the car fromsliding in a forward direction.

In the accompanying drawing: Figure 1 i is a side view partly broken away of an bra device embodying my invention; Fig. '2 a front view of the anti-skidding device proper; Fig. 3 a side view partly in section thereof; Fi l a similar view showing the parts in 'di erent positions; Fig. 5 a bottom view partly insection of the sleeve and cooperating parts; andFig. a detail of the Thedevice is shown to be secured to the casing 10 of the rear axle 11 of an automobile 12 although it may be attached to other parts of the vehicle body. To casing 10 is firmly secured by screwslS, a bipartite strap or fastening member 14; having two sets of, opposed depending bearings 15. Within the latter are. free to slide in "an axial direction, a pair of shaft-s16 to which are attached, by nuts 17, the hubs 18 of double arms 19. At their free ends, arms 19 are forked as at 20, to accommodate the upper ends of links 21, the parts 19, 21 constituting jointly a toggle. The forks 20 of each double arm 19 and the links 21 are connected by a transverse pin or pivot 22 carrying nuts 23, said pins constituting the toggle-knee. The' lower overlapping ends of each set of cooperating links 21 are perforated to receive the axle '24 of a trailer wheel 25. ,The latter may be of any desired Specification of Letters Patent.

configuration and may for instance be provided with a grooved tread as more fully described in a copending application filed by me on even date herewith under Serial Number 605,726. Each pair of arms 19 flanking the trailer 25 is connected by a spring 26 secured to pins 27 projecting laterally from said arms, said spring 26 tending to collapse the toggles 1.9, 21.

Wheel '25 may be lowered or raised 011' the ground by means of a hand lever 28, a locking pawl 29 of which is adapted to engage a toothed sector 30 having a smooth section 31. Lever 28 is by sectional rod 32 connected to an elbow lever 33 that loosely turns on one of the pins 22 and is provided with an elongated eye 34; straddling axle 24 of trailer 25. The sections .of rod 32 are connected by a spring 35 which constitute a yielding member intermediate the hand lever and the trailing device and thus compensates for occasional sagging etc. of the car frame when traveling over an uneven road be'd. automobile provided with an anti-skidding When the trailer is to be lowered into the position shown in Figs. 1 and 3, lever 28 is swung backward so that pawl 29 rides on the smooth section 31 of sector 30 to allow springs 26 a free play for collapsing the toggle 19, 21 and forthus forcing the trailing wheel against the road bed. When lever 28 is swung forward, pawl 29 rides over the toothed section of sector 30, and as soon as axle 24: has passed beyond a straight line drawn through the toggle-knee, springs 26 will collapse the toggle 19, 21 to automatically maintain the trailer wheel in its raised position. 1

Means are provided for increasing the frictional contact between wheel 25 and the road bed whenever the car commences to swerve to the right and left. These means are shown to consist of levers'36 thatturn loosely on pins 22 and areprovided at their free ends with rollers 37,. while cross pieces 38 arranged intermediate arms 19 maintain levers 36 properly -centered. Each roller 37 engages a pair of overlapping levers or tappets 39 that are pivot-ally secured to sleeve ioo 14 by screws 40 and have outer abutments ll. The latter are adaptedv to be engaged by pins or abutments19 projecting upwa'rdly from arms 19. Levers 36 are pro-' vided near their middle with laterally projecting pins 42 whichare connected by 'icomparatively strong springs 43 that act as spacers for said levers. 1

When the rear wheels 44: of the automobile start toswerve laterally, trailer 25 by being tightly forced against the road bed will not participate in this displacement, so thatLarelative axial movement between trailer 2'5.

and casing will take place. In. this way shaft 16 together with arms 19 and levers 36 will be axially shifted withinbearings 15,

" so that pins l9 by impinging against abutv respond glyfistraighten toggles 19, 21. "'20 ments 41 will swing levers 39 outward to correspondingly spread the roller carrying upper sections of levers 36. As springs 43 prevent-,{a spreading of the levers at the middle thereof, the lower endsof the arms .will thus-be moved toward each other to cor- It will be seen that the greater the swerving action-of the car, the more the toggles 19,

21 will bestraightened to gradually increase the frictional contact betweenthe trailer and the road bed.

For preventing a forward skidding of the automobile, wheel is provided with one or more: annular offsets or brake rims 4:5. Rim 45 1s straddled by a strap 4 6, one end of which is secured at 47 to one of the links 21 while its other end is secured to. a lug I 48 of'elbow leverj33 in proximity to its eye 34. .In operation, lever 28 is swung backward to tilt the lower arm of lever 33 downward and thereby tighten strap 46 around brake rim 45. v

It will be seen that by the construction described, any undesirable forward or lateral i skidding of the automobile is effectively prevented.
